Two Houston-area communities, Riverstone and Aliana, earned spots on a national ranking of the 20 top-selling communities in 2016, according to a new report.

Riverstone in the Sugar Land/Missouri City area logged 441 new home sales in 2016, down 28 percent from 609 sales in 2015, according to RCLCO, a housing consulting firm that surveys communities throughout the nation to determine the ranking. Riverstone ranked No. 18.

Aliana, off the Grand Parkway and Airport Boulevard southwest of Houston, registered 426 sales in 2016, down from 443 in 2015. The community ranked No. 19.

Seven other local communities are likely in the top 50, according to RCLCO. Among those, Riverstone was the only one to experience a precipitous decline in sales. RCLCO attributed the drop to a declining inventory of homes in the lower price range as builders complete the community with more expensive homes.

The only other Texas communities on the list are in the Dallas-Fort Worth area: Westridge, No. 8 with 528 sales, and Paloma Creek, No. 9 with 515 sales.
